MB 600-250A – Inch Series


KOENIG EXPANDER® plugs effectively seal drilled holes. These parts feature a serrated sleeve which expands as the ball is inserted, enlarging the part to the needed size and sealing the hole. For installation, push-style expanders require a hole drilled with a counter bore.
